Definitions

  • gearboxes In order to monitor and ensure a reliable function, gearboxes sometimes have numerous sensors or actuators installed on rotating components, which are supplied with power in accordance with conventional solutions via slip ring connections or connected to data lines.
  • slip rings For example, for operation of pitch drive and control systems electrical energy is required, which is transmitted in conventional wind turbines via slip rings from the nacelle to arranged in the rotor hub electrical consumers.
  • the slip rings often transmit status and control signals to the pitch drive and control systems.
  • Slip rings are subject to mechanical wear and represent a significant potential source of interference in a wind turbine.
  • Out DE 10 2004 051 170 A1 is a computed tomography device with a rotating part with an X-ray tube and a detector for detecting the transmitted X-radiation known.
  • a stationary part of the computed tomography device is connected to a data processing device for evaluating the detected measurement results.
  • a transformer is provided, which allows a contactless electrical power transmission between the stationary and the rotating part.
  • the transmitter is designed in addition to the contactless electrical power transmission for a contactless data transmission between the stationary and the rotating part.
  • the device comprises a transmitting device with at least one transmitting antenna connected to a transmitter and a receiving device with a receiving antenna connected to a receiver.
  • the transmitting antenna and the receiving antenna are in the form of a radio-frequency line and are arranged such that signals fed into the transmitting antenna during at least a portion of the relative movement are received by capacitive or inductive coupling from the receiving antenna.
  • one or more compensation devices are arranged, which counteract a signal distortion caused by the transmission of the signals on the high-frequency line.
  • WO 2005031770 A1 is known an inductive rotary transformer, which consists of a fixed part and a rotating part, wherein the rotating part and the fixed part have a common virtual axis of rotation.
  • the rotating part rotates around the fixed part.
  • the data transmission takes place via at least one data transmission path by means of at least one inductive element.
  • the data transmission path is arranged outside the axis of rotation of the rotary transformer.
  • WO 2007/012568 A2 is a device for data transmission between two relatively moving components, of which a first component has a plurality of transmitting segments arranged along a direction of movement and a second component has a plurality of receiving units arranged along the direction of movement.
  • the data is divided into several transmission segments for parallel transmission.
  • the data will be transmitted in data packets which, in addition to a data portion, comprise at least one packet ID, by means of which the data portions of the data packets in a receiving device connected to the receiving units are assembled in the correct order.
  • the present invention has for its object to provide a modular system of transmission components for energy or data transmission between relatively rotating gear parts, which allows a cost-effective and easy realization of different power classes.
  • the series of transmission components comprises a base module used in all types of transmission components of the series, which has a feeding primary part as the transmitting unit and a secondary part as the receiving unit.
  • the transmitting unit and the receiving unit are separated by at least one air gap, each in a substantially ring or disc-shaped carrier fixed and inductive, capacitive, optical or radio-coupled with each other.
  • the carriers can be arranged around a gear shaft.
  • Gear parts are, for example, arranged in a transmission machine elements or connected to a transmission machine elements, in particular connected to a drive or output shaft components. Between two carriers a rolling or sliding bearing is arranged.
  • Transmission component types are each characterized by a type-specific number distributed in the circumferential direction of the carriers arranged base modules.
  • transmission component types are each characterized by a type-specific number radially offset from one another arranged rows of base modules.

  • FIG. 1 a gondola of a wind turbine is shown, in which a transmission 1 and a generator 2 are mounted.
  • the transmission 1 is connected via a drive shaft 11 with a rotor hub 4, in which a plurality of pitch drive systems 4 are arranged for rotor blade adjustment.
  • the transmission 1 is connected via an output shaft 12 and a clutch 13 to the generator 2.
